Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000393- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
394 start byte and the continuation byte(s) are now considered invalid, instead
395 of the number of bytes specified by the start byte.
396 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
397 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
398 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
399 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000407- Issue #8748: Fix two issues with comparisons between complex and integer
408 objects. (1) The comparison could incorrectly return True in some cases
409 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
410 (2) The comparison raised an OverflowError for large integers, leading
411 to unpredictable exceptions when combining integers and complex objects
412 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +0000414- Issue #5211: Implicit coercion for the complex type is now completely
415 removed. (Coercion for arithmetic operations was already removed in 2.7
416 alpha 4, but coercion for rich comparisons was accidentally left in.)

Georg Brandlfee0f442010-05-22 21:26:21 +0000608- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
609 operation raises multiple signals and more than one of those signals is
610 trapped, the specification determines the order in which the signals should be
611 handled. In many cases this order wasn't being followed, leading to the wrong
612 Python exception being raised.

798 with a non-empty format string. This is an effort to future-proof user
799 code. If a derived class does not currently implement __format__ but later
800 adds its own __format__, it would most likely break user code that had
801 supplied a format string. This will be changed to a DeprecationWaring in
802 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +0000852- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
853 InvalidOperation instead of returning False. (Comparisons involving a quiet
854 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
855 signaling NaNs remain unhashable.

858 return a result based on the numeric values of the operands; previously they
859 returned an arbitrary result based on the relative ordering of id(float) and
860 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000862- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000863 argument `-` which tells it to read files to compile from stdin. Each line is
864 read on demand and the named file is compiled immediately. (Original patch by
865 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000874- Comparisons using one of <, <=, >, >= between a complex instance and a
875 Fractions instance now raise TypeError instead of returning True/False. This
876 makes Fraction <=> complex comparisons consistent with int <=> complex, float
877 <=> complex, and complex <=> complex comparisons.

986 the set of integer codes for which it was used differed between native packing
987 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001235- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1236 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1237 returning NULL. The macro now returns a statically allocated empty string
1238 instead.

1248 strings,
1249 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1250 numeric strings corresponding to subnormal values,
1251 (3) a memory leak for some values large enough to cause overflow, and
1252 (4) a number of flaws that could lead to incorrectly rounded results.

1271
Georg Brandlba83f822010-03-14 09:50:54 +00001272- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

Antoine Pitroud840e512010-02-04 20:20:18 +00001283- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001284 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001285 Also, raise ValueError rather than TypeError when an unknown TIPC address
1286 type is specified. Patch by Brian Curtin.

Georg Brandlba83f822010-03-14 09:50:54 +00001291 file position when calling `truncate()`. It would previously change the file
1292 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001293 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1294
Georg Brandlba83f822010-03-14 09:50:54 +00001295- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1296 class used to represent files stored inside an archive. The new
1297 implementation is significantly faster and can be wrapped in a
1298 ``io.BufferedReader`` object for more speedups. It also solves an issue
1299 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001310- Issue #7748: Since unicode values are supported for some metadata options in
1311 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1312 encoded string for them. This ensures that the upload and register commands
1313 send the correct values to PyPI without any error.

1388-----------------
1389
Georg Brandlba83f822010-03-14 09:50:54 +00001390- The ``__complex__()`` method is now looked up on the class of instances to
1391 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001393- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1394 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1395
Mark Dickinson1b34d252010-01-01 17:27:30 +00001396- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001397 DeprecationWarning when passed a float argument where an integer was expected.
1398 These functions and methods now raise TypeError instead. The majority of the
1399 effects of this change are in the extension modules, but some core functions
1400 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1401 and many unicode/str methods.

1413
Georg Brandlba83f822010-03-14 09:50:54 +00001414- Issue #1811: Improve accuracy and cross-platform consistency for true division
1415 of integers: the result of a/b is now correctly rounded for ints a and b (at
1416 least on IEEE 754 platforms), and in particular does not depend on the
1417 internal representation of a long.

1425
Georg Brandlba83f822010-03-14 09:50:54 +00001426 These executables now work properly with the arch(1) command: ``arch -ppc
1427 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00001563- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1564 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001565
Georg Brandlba83f822010-03-14 09:50:54 +00001566- Issue #3382: 'F' formatting for float and complex now convert the result to
1567 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1568 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001569
Georg Brandlba83f822010-03-14 09:50:54 +00001570- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1571 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001572
Georg Brandlba83f822010-03-14 09:50:54 +00001573- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1574 1e-100 used to raise OverflowError, but now gives the requested 120
1575 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001576
Georg Brandlba83f822010-03-14 09:50:54 +00001577- Add Py3k warnings for parameter names in parentheses.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00001578
Georg Brandlba83f822010-03-14 09:50:54 +00001579- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00001580
Georg Brandlba83f822010-03-14 09:50:54 +00001581- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
1582 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001583
Georg Brandlba83f822010-03-14 09:50:54 +00001584- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1585 decimal string that's guaranteed to round back to x under correct rounding
1586 (with round-half-to-even rounding mode). Previously it gave a string based on
1587 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1588 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1589 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001590
Georg Brandlba83f822010-03-14 09:50:54 +00001591- Issue #7117: On almost all platforms: float-to-string and string-to-float
1592 conversions within Python are now correctly rounded. Places these conversions
1593 occur include: str for floats and complex numbers; the float and complex
1594 constructors; old-style and new-style numeric formatting; serialization and
1595 deserialization of floats and complex numbers using marshal, pickle and json;
1596 parsing of float and imaginary literals in Python code; Decimal-to-float
1597 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001598
Georg Brandlba83f822010-03-14 09:50:54 +00001599 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1600 providing correctly-rounded strtod and dtoa C functions. This code is
1601 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1602 the C compiler. There may be a small number of platforms on which correct
1603 operation of this code cannot be guaranteed, so the code is not used: notably,
1604 this applies to platforms where the C double format is not IEEE 754 binary64,
1605 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1606 and Python's configure script is unable to determine how to change the FPU
1607 precision. On these platforms conversions use the platform strtod and dtoa,
1608 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001609
Georg Brandlba83f822010-03-14 09:50:54 +00001610- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1611 uses the correctly-rounded string <-> float conversions described above (when
1612 available), and so produces correctly rounded results that will display nicely
1613 under the float repr. There are two related small changes: (1) round now
1614 accepts any class with an ``__index__()`` method for its second argument (but
1615 no longer accepts floats for the second argument), and (2) an excessively
1616 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1617 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +00001618
Philip Jenveyfab8be22009-11-17 02:42:26 +00001619- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
1620
Georg Brandlba83f822010-03-14 09:50:54 +00001621- Fix several issues with ``compile()``. The input can now contain Windows and
1622 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00001623
Georg Brandlba83f822010-03-14 09:50:54 +00001624- Remove length limitation when constructing a complex number from a unicode
1625 string.
Mark Dickinsonc04c7c52009-10-26 22:28:14 +00001626
Georg Brandlba83f822010-03-14 09:50:54 +00001627- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised
1628 during the formation of an output tuple.
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +00001629
Mark Dickinson8d87dc02009-10-25 20:39:06 +00001630- Issue #1087418: Boost performance of bitwise operations for longs.
1631
Georg Brandlba83f822010-03-14 09:50:54 +00001632- Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``,
1633 which fixes the problem of some exceptions being thrown at shutdown when the
1634 interpreter is killed. Patch by Adam Olsen.
Antoine Pitrouefb60c02009-10-20 21:29:37 +00001635
Georg Brandlba83f822010-03-14 09:50:54 +00001636- Issue #7168: Document ``PyFloat_AsString()`` and ``PyFloat_AsReprString()``,
1637 and note that they are unsafe and deprecated.
Eric Smithc12781a2009-10-19 14:38:14 +00001638
Georg Brandlba83f822010-03-14 09:50:54 +00001639- Issue #7120: logging: Remove import of multiprocessing which is causing crash
1640 in GAE.
Vinay Sajip03d5c342009-10-16 14:06:44 +00001641
Georg Brandlba83f822010-03-14 09:50:54 +00001642- Issue #7140: The ``__dict__`` of a module should not be cleared unless the
1643 module is the only object holding a reference to it.
Benjamin Peterson196b0922009-10-15 15:44:46 +00001644
Georg Brandlba83f822010-03-14 09:50:54 +00001645- Issue #1754094: Improve the stack depth calculation in the compiler. There
1646 should be no other effect than a small decrease in memory use. Patch by
1647 Christopher Tur Lesniewski-Laas.
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +00001648
Georg Brandlba83f822010-03-14 09:50:54 +00001649- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
1650 and mutating it from another one. Patch by Scott Dial.
Antoine Pitroubeaf6a02009-10-11 21:03:26 +00001651
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00001652- Issue #1571184: The Unicode database contains properties for more characters.
1653 The tables for code points representing numeric values, white spaces or line
1654 breaks are now generated from the official Unicode Character Database files,
1655 and include information from the Unihan.txt file.
1656

1661 running through the shell. Patch by Jean-Paul Calderone and Jani Hakala.
Philip Jenvey8b902042009-09-29 19:10:15 +00001662
Georg Brandlba83f822010-03-14 09:50:54 +00001663- Issue #7019: Raise ValueError when unmarshalling bad long data, instead of

1712 build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead
1713 of stdint.h on that platform.
Mark Dickinson2f865b92009-06-30 15:32:30 +00001714

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001759
Georg Brandlba83f822010-03-14 09:50:54 +00001760 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1761 (2) parsing of strings representing infinities and nans was locale aware; and
1762 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001764- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1765 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1766 but with at least one decimal point and with a default precision
1767 of 12. Previously, the behavior the same but with a default precision of 6.
1768 This more closely matches ``str()``, and reduces surprises when adding
1769 alignment flags to the empty presentation type. This also affects the new
1770 complex.__format__ in the same way.
1771
1772- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1773 classtype's, even if it was None. property now inserts the __doc__ into the

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003400- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3401 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3402 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3403 ``printf`` function, whereas PyString_FromFormat has an independent
3404 implementation and uses "%zd" on all platforms for size_t values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003408- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3409 error.
3410
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003411- Issue #3777: long() applied to a float object now always return a long
3412 object; previously an int would be returned for small values. the __long__
3413 method is allowed to return either an int or a long, but the behaviour of
3414 float objects should not change to respect backward compatibility.
3415
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003416- Issue #3751: str.rpartition would perform a left-partition when called with
3417 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003421- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003422 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003423 was correctly parsed but parsing of subsequent arguments failed.
3424
Vinay Sajip35e3b032008-09-01 14:33:59 +00003425- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003426 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3427 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3428 when given a tuple of classes as second argument, were looking up
3429 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3430 type object.
3431
Neal Norwitz18aa3882008-08-24 05:04:52 +00003432- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003501 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3502 for catch_warnings() also led to an improvement in the raising of a
3503 DeprecationWarning related to warnings.warn_explicit().
3504

3531
Benjamin Peterson37346b22008-08-23 20:27:43 +00003532- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003569What's New in Python 2.6 beta 3?
3570================================
3571
Barry Warsaw07a4a382008-08-21 01:15:08 +00003572*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003573
3574Core and Builtins
3575-----------------
3576
Guido van Rossumf8402962008-08-20 15:01:50 +00003577- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3578 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3579 extensions do not automatically benefit from the class attribute
3580 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3581 to their tp_flags field if they care. This is a backwards
3582 compatibility feature; in 3.0, all types will use the cache by
3583 default.
3584
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003585- Keyword arguments can now follow starred arguments. (``f(a, *args,
3586 keyword=23)`` is now valid syntax.)
3587
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003588- ctypes function pointers that are COM methods have a boolean True
3589 value again.
3590
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003591- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3592 by denying s# to parse objects that have a releasebuffer procedure,
3593 and introducing s*.
3594
Georg Brandl1e13ea92008-08-11 09:07:59 +00003595- Issue #3537: Fix an assertion failure when an empty but presized dict
3596 object was stored in the freelist.
3597
Mark Dickinsonb6467572008-08-04 21:30:09 +00003598- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3599 ValueError consistently across platforms.
3600
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003601- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3602 (64bit Unix, for example), unichr() would truncate its argument and return
3603 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3604
Neal Norwitze7d8be82008-07-31 17:17:14 +00003605- Apply security patches from Apple.
3606
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003607- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3608 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3609
Antoine Pitrou92f82162008-07-25 22:22:08 +00003610- Issue #1819: function calls with several named parameters are now on
3611 average 35% faster (as measured by pybench).
3612
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003613- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3614 the python debugger steps into a class statement: the free variables (local
3615 variables defined in an outer scope) would be deleted from the outer scope.
3616
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003617- Issue #2620: Overflow checking when allocating or reallocating memory
3618 was not always being done properly in some python types and extension
3619 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3620 all been updated to perform better checks and places in the code that
3621 would previously leak memory on the error path when such an allocation
3622 failed have been fixed.

3625-------
3626
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003627- Issue #3612: Added some missing basic types in ctypes.wintypes.
3628
Benjamin Petersone977ad42008-08-20 01:42:01 +00003629- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3630 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3631
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003632- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3633 version reported by these tools does not necessarily follow the python
3634 version numbering scheme, so the module is less strict when parsing it.
3635
Nick Coghlanf70385a2008-08-18 12:42:46 +00003636- Issue #2235: Added Py3k warnings for types which will become unhashable
3637 under the stricter __hash__ inheritance rules in 3.0. Several types
3638 which did not meet the rules for hash invariants and were already
3639 unhashable in 3.0 have now been explicitly flagged as unhashable in
3640 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3641 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3642
Brett Cannon88f801d2008-08-18 00:46:22 +00003643- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3644 imported into the module but exposed as part of the module's API.
3645
Brett Cannon7b96f072008-08-18 00:41:11 +00003646- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3647
Brett Cannon46225e72008-08-18 00:36:52 +00003648- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

3651
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003652- Issue #3575: Incremental decoder's decode function now takes bytearray
3653 by using 's*' instead of 't#'.
3654
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003655- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003656 fails unicode conversion on 2nd parameter. (windows only)
3657
Georg Brandl222e2082010-08-01 22:27:39 +00003658- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003659 in a redirect.
3660
Brett Cannonabe423e2008-08-16 21:47:07 +00003661- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003662 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003663
Facundo Batistaeb90b782008-08-16 14:44:07 +00003664- Issue #2776: fixed small issue when handling an URL with double slash
3665 after a 302 response in the case of not going through a proxy.
3666
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003667- Issue #2676: in the email package, content-type parsing was hanging on
3668 pathological input because of quadratic or exponential behaviour of a
3669 regular expression.
3670
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003671- Issue #3476: binary buffered reading through the new "io" library is now
3672 thread-safe.
3673
Brett Cannonbf3157b2008-08-14 05:00:03 +00003674- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3675 since mimetools itself is deprecated. Because modules are cached, all
3676 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3677
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003678- Issue #3134: shutil referenced undefined WindowsError symbol.
3679
Robert Schuppenies14646332008-08-10 11:01:53 +00003680- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3681 menu entries were not deleted.
3682
Brett Cannon83e81842008-08-09 23:30:55 +00003683- Copied the implementation of reduce() to _functools.reduce() to have a
3684 version that did not raise a DeprecationWarning under -3.
3685
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003686- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3687 a MemoryError rather than silently stop the iteration.
3688
Guido van Rossum59ce9012008-08-09 14:55:34 +00003689- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3690 to _sre.compile() will now be rejected. This should not affect anybody
3691 since the re.compile() function never generates invalid re-bytecode.

3769-----------------
3770
Georg Brandl3e483f62008-07-16 22:57:41 +00003771- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3772 its methods now allow for items objects that can be converted to
3773 an integer using operator.index().
3774
Mark Dickinson64b7e502008-07-16 09:40:03 +00003775- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3776 produced a ValueError instead of giving the correct float.
3777
Eric Smitha5fa5a22008-07-16 00:11:49 +00003778- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3779 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3780
Mark Dickinson7103aa42008-07-15 19:08:33 +00003781- Issue #3008: the float type has a new instance method 'float.hex'
3782 and a new class method 'float.fromhex' to convert floating-point
3783 numbers to and from hexadecimal strings, respectively.
3784
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003785- Issue #2235: __hash__ is once again inherited by default. To allow
3786 collections.Hashable to remain meaningful in the presence of the
3787 default hash implementation (object.__hash__), it is now possible
3788 to explicit block inheritance of hash by setting __hash__=None at
3789 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3790 level.
3791
Nick Coghlanb028f502008-07-13 14:52:36 +00003792- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3793 the parent module cannot be found while performing an absolute import.
3794 This means that an incorrectly defined __package__ attribute will
3795 now only prevent relative imports in that module rather than causing
3796 all imports from that module to fail.
3797
Nick Coghlan14ff9942008-07-08 14:21:42 +00003798- Issue #2517: Allow unicode messages in Exceptions again by correctly

3808 another thread's dictionary.
3809
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003810- Issue #3004: Minor change to slice.indices(): the start and stop
3811 arguments are now treated identically, making the behaviour easier
3812 to describe and understand. For example, slice(None, -10,
3813 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3814 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3815 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00003817- Issue #3219: Calling a function with repeated keyword arguments,
3818 f(a=2, a=23), would not cause a syntax error. This was a regression
3819 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003857- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3858 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003859 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003860 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003876- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4264
Brett Cannonb61d8012008-05-11 23:39:04 +00004265- ``Lib/lib-old`` is now added to sys.path.
4266
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004267- On MacOS X it is now possible to install the framework in 64-bit
4268 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004269 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004270
4271 This is controlled by the configure argument ``--with-universal-archs``:
4272
4273 - ``--with-universal-archs=all``: install 4-way universal
4274
4275 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4276
4277 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4278
4279 This option should be used in combination with ``--enable-universalsdk=``.
4280
4281 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00004290
4291- The PyString functions have been renamed to PyBytes. A batch of
4292 defines were added so that the linker still sees the original
4293 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004331- Issue #1631171: Re-implement the 'warnings' module in C (the
4332 original Python code has been kept as backup). This will allow for
4333 using the 'warning's machinery in such places as the parser where
4334 use of pure Python code is not possible. Both the ``showarning()``
4335 and ``formatwarning()`` gain an optional 'line' argument which is
4336 not called by default for backwards-compatibility reasons. Setting
4337 ``warnings.showwarning()`` to an implementation that lacks support
4338 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004363- The getpass module has been improved on Unix. It now uses /dev/tty
4364 by default and uses stderr instead of stdout. A GetPassWarning is
4365 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004380- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004381 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004401- Issue #2550: The approach used by client/server code for obtaining
4402 ports to listen on in network-oriented tests has been refined in an
4403 effort to facilitate running multiple instances of the entire
4404 regression test suite in parallel without issue.
4405 test_support.bind_port() has been fixed such that it will always
4406 return a unique port -- which wasn't always the case with the
4407 previous implementation, especially if socket options had been set
4408 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4409 new implementation of bind_port() will actually raise an exception
4410 if it is passed an AF_INET/SOCK_STREAM socket with either the
4411 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4412 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4413 the socket it's been passed. This currently only applies to
4414 Windows. This option prevents any other sockets from binding to the
4415 host/port we've bound to, thus removing the possibility of the
4416 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4417 when a second SOCK_STREAM socket binds and accepts to a host/port
4418 that's already been bound by another socket. The optional preferred
4419 port parameter to bind_port() has been removed. Under no
4420 circumstances should tests be hard coding ports!
4421
4422 test_support.find_unused_port() has also been introduced, which will
4423 pass a temporary socket object to bind_port() in order to obtain an
4424 unused port. The temporary socket object is then closed and
4425 deleted, and the port is returned. This method should only be used
4426 for obtaining an unused port in order to pass to an external program
4427 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4428 a parameter to a server-oriented class that doesn't give you direct
4429 access to the underlying socket used.
4430
4431 Finally, test_support.HOST has been introduced, which should be used
4432 for the host argument of any relevant socket calls (i.e. bind and
4433 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004434
4435 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004436 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004437 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4438 test_asynchat and test_socket_ssl.
4439
Georg Brandl3ee81df2008-05-17 18:14:43 +00004440 It is now possible for multiple instances of the regression test
4441 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004720- Added the future_builtins module, which contains hex() and oct().
4721 These are the PEP 3127 version of these functions, designed to be
4722 compatible with the hex() and oct() builtins from Python 3.0. They
4723 differ slightly in their output formats from the existing, unchanged
4724 Python 2.6 builtins. The expected usage of the future_builtins
4725 module is:
4726 from future_builtins import hex, oct
4727
Eric Smith7ef40bf2008-02-20 23:34:22 +00004728- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4729 exponents for exponents with absolute value < 100. Follows C99
4730 standard. This is a change on Windows, which would use 3 digits.
4731 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4732 so that any alterations it does to the resulting string will be
4733 available in stringlib/formatter.h (for float.__format__).
4734
Eric Smith5a3c1352008-02-19 13:21:56 +00004735- Implemented PEP 3101, Advanced String Formatting. This adds a new
4736 builtin format(); a format() method for str and unicode; a
4737 __format__() method to object, str, unicode, int, long, float, and
4738 datetime; the class string.Formatter; and the C API
4739 PyObject_Format().
4740
Georg Brandl3ee81df2008-05-17 18:14:43 +00004741- Fixed several potential crashes, all caused by specially crafted
4742 __del__ methods exploiting objects in temporarily inconsistent
4743 state.

4754 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004755
Georg Brandl3ee81df2008-05-17 18:14:43 +00004756- Issue #2045: Fix an infinite recursion triggered when printing a
4757 subclass of collections.defaultdict, if its default_factory is set
4758 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004759
Christian Heimesf75dbef2008-02-08 00:11:31 +00004760- Fixed a minor memory leak in dictobject.c. The content of the free
4761 list was not freed on interpreter shutdown.
4762
Georg Brandl21e99f42010-03-07 15:23:59 +00004763- Limit free list of method and built-in function objects to 256

4767 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004768 to compact the internal free lists of pre-allocted ints and floats.
4769
Georg Brandl3ee81df2008-05-17 18:14:43 +00004770- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4771 calls. Python expected the return type int but the fork familie

Georg Brandl3ee81df2008-05-17 18:14:43 +00004783- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4784 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004785
Georg Brandl3ee81df2008-05-17 18:14:43 +00004786- Patch #1473257: generator objects gain a gi_code attribute. This is
4787 the same object as the func_code attribute of the function that
4788 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004789
Georg Brandl3ee81df2008-05-17 18:14:43 +00004790- Issue #1920: "while 0" statements were completely removed by the
4791 compiler, even in the presence of an "else" clause, which is
4792 supposed to be run when the condition is false. Now the compiler
4793 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004794
Guido van Rossumeead05f2008-01-24 18:21:02 +00004795- A few crashers fixed: weakref_in_del.py (issue #1377858);
4796 loosing_dict_ref.py (issue #1303614, test67.py);
4797 borrowed_ref_[34].py (not in tracker).
4798
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004799- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004800 suppressed while an extension is loaded by calling SetErrorMode in
4801 dynload_win.c. The error is still reported properly.
4802
Georg Brandl3ee81df2008-05-17 18:14:43 +00004803- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004804 several extension methods and modules do not work without unicode
4805 support.
4806
Georg Brandl26543b12008-01-21 18:36:51 +00004807- Issue #1882: when compiling code from a string, encoding cookies in the
4808 second line of code were not always recognized correctly.
4809
Georg Brandl14404b62008-01-19 19:27:05 +00004810- Issue #1679: "0x" was taken as a valid integer literal.
4811
Georg Brandl6caad7d2008-01-26 14:19:22 +00004812- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004813 added.
4814
Christian Heimesc94e2b52008-01-14 04:13:37 +00004815- sys.float_info / PyFloat_GetInfo: The floating point information
4816 object was converted from a dict to a specialized structseq object.
4817
Georg Brandl3ee81df2008-05-17 18:14:43 +00004818- Patch #1816: Added sys.flags structseq. It exposes the status of
4819 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004820
Georg Brandl3ee81df2008-05-17 18:14:43 +00004821- Objects/structseq.c: Implemented new structseq representation. The
4822 patch makes structseqs (e.g. the return value of os.stat) more
4823 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004824
Georg Brandl3ee81df2008-05-17 18:14:43 +00004825- Patch #1700288: added a type attribute cache that caches method
4826 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004827
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004828- Bug #1776: __import__() no longer accepts filenames on any platform.
4829 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004830
Georg Brandlaed6c662008-01-07 17:25:53 +00004831- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4832
Georg Brandl3ee81df2008-05-17 18:14:43 +00004833- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4834 envvar and sys.dont_write_bytecode attribute. All these can be set
4835 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004836
Georg Brandl3ee81df2008-05-17 18:14:43 +00004837- Improve some exception messages when Windows fails to load an
4838 extension module. Now we get for example '%1 is not a valid Win32
4839 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004846- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004847 and INF. float("nan"), float("inf") and float("-inf") now work on
4848 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004849
Georg Brandl3ee81df2008-05-17 18:14:43 +00004850- Compiler now generates simpler and faster code for dictionary
4851 literals. The oparg for BUILD_MAP now indicates an estimated
4852 dictionary size. There is a new opcode, STORE_MAP, for adding
4853 entries to the dictionary.

4865
Nick Coghlanef01d822007-12-03 12:55:17 +00004866- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00004882- Patch #1739468: Directories and zipfiles containing a __main__.py
4883 file can now be directly executed by passing their name to the
4884 interpreter. The directory/zipfile is automatically inserted as the
4885 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004886
Georg Brandl3ee81df2008-05-17 18:14:43 +00004887- Issue #1265: Fix a problem with sys.settrace, if the tracing
4888 function uses a generator expression when at the same time the
4889 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004890
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004891- sets and frozensets now have an isdisjoint() method.
4892
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004893- optimize the performance of builtin.sum().
4894
Neal Norwitz44f326e2007-10-05 05:29:17 +00004895- Fix warnings found by the new version of the Coverity checker.
4896
Georg Brandl21e99f42010-03-07 15:23:59 +00004897- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004898 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4899 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004900
Georg Brandl3ee81df2008-05-17 18:14:43 +00004901- Issue #1686386: Tuple's tp_repr did not take into account the
4902 possibility of having a self-referential tuple, which is possible
4903 from C code. Nor did object's tp_str consider that a type's tp_str
4904 could do something that could lead to an inifinite recursion.
4905 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4906 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004907
Georg Brandl3ee81df2008-05-17 18:14:43 +00004908- Issue #1164: It was possible to trigger deadlock when using the
4909 'print' statement to write to a file since the GIL was not released
4910 as needed. Now PyObject_Print() does the right thing along with
4911 various tp_print implementations of the built-in types and those in
4912 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004913
Georg Brandl3ee81df2008-05-17 18:14:43 +00004914- Issue #1147: Exceptions were directly allowing string exceptions in
4915 their throw() method even though string exceptions no longer
4916 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004917
Georg Brandl3ee81df2008-05-17 18:14:43 +00004918- Issue #1096: Prevent a segfault from getting the repr of a very
4919 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004920
Brett Cannon1e534b52007-09-07 04:18:30 +00004921- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004922 PyObject_Call() never calling back out to Python code to trigger
4923 recursion depth updates/checks. Required the creation of a static
4924 RuntimeError instance in case normalizing an exception put the
4925 recursion check value past its limit. Fixes crashers
4926 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004927

Neal Norwitz0ac60192007-05-27 04:08:54 +00004941- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004942 __*__ attributes. (Some already existed, e.g., __doc__ and
4943 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004944
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004945- Add -3 option to the interpreter to warn about features that are
4946 deprecated and will be changed/removed in Python 3.0.
4947
Georg Brandl2134e752007-05-21 20:34:16 +00004948- Patch #1686487: you can now pass any mapping after '**' in function
4949 calls.
4950
Collin Winter62903052007-05-18 23:11:24 +00004951- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004952 "except E as target:". This is to provide forwards compatibility
4953 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00004955- Deprecate BaseException.message as per PEP 352.
4956
Georg Brandl3ee81df2008-05-17 18:14:43 +00004957- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004958 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004959
Vinay Sajip8549ce32007-05-06 17:53:37 +00004960- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004961 setting a plain string, ie don't expand to single letter identifiers.
4962
Raymond Hettinger13936692007-04-11 18:40:58 +00004963- Request #1191699: Slices can now be pickled.
4964
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004965- Request #1193128: str.translate() now allows a None argument for
4966 translations that only remove characters without re-mapping the
4967 remaining characters.
4968
Georg Brandl5cb76c12007-03-21 09:00:39 +00004969- Patch #1682205: a TypeError while unpacking an iterable is no longer
4970 masked by a generic one with the message "unpack non-sequence".
4971
Neal Norwitzaa754b72007-03-21 06:39:48 +00004972- Remove unused file Python/fmod.c.
4973
Guido van Rossum143b5642007-03-23 04:58:42 +00004974- Bug #1683368: The object.__init__() and object.__new__() methods are
4975 now stricter in rejecting excess arguments. The only time when
4976 either allows excess arguments is when it is not overridden and the
4977 other one is. For backwards compatibility, when both are
4978 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004979 warning later). Also, type.__init__() insists on the same signature
4980 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004981
Georg Brandl3ee81df2008-05-17 18:14:43 +00004982- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4983 object to complex using its __complex__() method before falling back
4984 to the __float__() method. Therefore, the functions in the cmath
4985 module now can operate on objects that define a __complex__()
4986 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004988- Patch #1623563: allow __class__ assignment for classes with
4989 __slots__. The old and the new class are still required to have the
4990 same slot names.

5003
Georg Brandl7b9c5552007-03-12 14:30:05 +00005004- Bug #1678647: write a newline after printing an exception in any
5005 case, even when converting the value to a string failed.
5006
Georg Brandl871f1bc2007-03-12 13:17:36 +00005007- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005008 its argument, if it exists. If not, it will work like before. This
5009 allows customizing the output of dir() in the presence of a
5010 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00005125- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005143 generator expressions (x for x, in ... ) works again. Fixing this
5144 problem required changing the .pyc magic number. This means that
5145 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00005184- Removed uses of dict.has_key() from distutils, and uses of

Facundo Batistad918a652007-04-24 13:54:38 +00005533- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005534 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005575 AttributeError instead of an IOError when the server's response
5576 didn't contain a valid HTTP status line.

5667 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006060 time so that opening a database previously created with the DB_DUP
6061 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6062 opens. Specifically: dictionary assignment to a DB object will
6063 replace all values for a given key when the database allows
6064 duplicate values. DB users should use DB.put(k, v) when they want
6065 to store duplicates; not DB[k] = v.

6072 characters with ASCII value less than 32. Also, it correctly quotes
6073 dots only if they occur on a single line, as opposed to the previous
6074 behavior of quoting dots if they are the second character of any
6075 line.
